This invention relates to a tilting reflec-- tor construction particularly adapted to small and cheaply constructed automobile lamps, whereby the reflector may be oper ated from the dash to tilt it so as to direct the light straight forward substantially parallel with the road and to ermit it to return to normal position for directing the light downwardly at an angle to prevent the glare from blindin the passerbyf j The particular eature of this invention lies in the construction and manner of mounting the reflector in the lamp casing, andthe mechanism operable from the dash for actuating the reflector, whereby dust will be prevented from seeping into the casing through which the operating device passes, or around the reflector or reflector ring.

Another feature of the invention is the arrangement of the'manually controlled -actuating mechanism whereby the reflectors will be positively and completely actuated regardless of the position or torsion of the frame, and the variation in the rods -or cables is compensated for. This construction will also permit the adjustment of the lamps without afl'ecting of the reflector to the casing.

Still another feature relates to the mounting of the reflector to prevent rattling from any vibration that maybe set up 111 the lamp, which is accomplished by the-use of two supports at the top where there is the greatest vibration, and a positive connection with the actuating mechanism at the bottom.

The full nature of thisinvention will be understood from the-accompanying drawings and the following description and claims. I

In the drawings Fig. 1 is a central vertical cross section through a lamp showing, the reflector in normal position. Fig. 2 is a front elevation of the lamp with the edge portion of a portion of the closure removed. Fig. 3 is a section taken on the line 3-3 of Fig. 2. Fig. 4 is a section taken on the. line -.44- of Fig. 1. Fig. 5 is a plan View or the reflector control from the dash. F ig. 6 is a section taken on the line 66 of Fig. 5.

In the drawings there is shown a lamp having a. casing 10 provided with an. annular bead 11' and laterally extending flange portion 12. Mounted in the casing there is 13 secured therea reflector containing ring 'as shovm herein in in any suitable manner, by the wire retaining ring 14:. Said ring 13 is provided with the usual annular groove, in which is mounted a sealing guard 15 against which the lens 16 abuts and is securely held in position by the lens rim or lens closure 17. The closure 17 is provided with in-v wardly extending lens engaging fingers 18 which hold the lens in position and is provided with an outer flange ortion adapted to telescope over the casing ii "secured in position thereon by the inwardly and radially extendin pins 19 extending through suitable slots in said flange in the usual manner. The construction above described is that commonly employed on lamps of this character or may be changed to an other construction it so desired without a footing this invention. 1

For pivotally supporting the reflector in said casing, there isahinge spring 20 shown in Fig. 3 secured in" any suitable manner to the reflector containing ring 13, as shown herein by the rivets 21. As shown in Fig. 2 there are two pivot points, one on each side of the center of'the lamp toward the top the relative position thereof wherein the hingespring is mounted. Said spring is arranged to encircle the rearwaidly extending flange portion of the reflector containing ring and "engage and hold against said flange portion. the in wardly turned edge 22 of the reflector 23', whereby said reflector will be suspended by said ring so as to swing therefrom in a vertical plane. The spring tension of the bin spring 20 yieldingly secures the top of t e reflector at pressed portion 24 of the ring 13. The relative diameters of the reflector and the rin 13 are such that the reflector is permitted to move freely therein and is spaced slightly awlsjiy' from said ring, as shown in Fig. 1.

ounted in the reflector ange 12 and be its hinge points against a dethere is the usual no rearwardly extending sleeve in which is slidably mounted a bayonet slotted lamp socket 26 adapted to hold the lamp 27 The socket is connected in the usual manner by the plug 28 and wires 29 to the plug 30 for the desired electrical connection. For focusin the lamp 27 in the reflector there is provi ed an ear 31 projecting from the socket 26 through a slot in the sleeve 25 through which the screw 32, which i s mounted in an ear 33 formed on said sleeve, .is adapted to screw for sliding the socket forwardly and rearwardly in said sleeve. At the rear of the casing there is an opening plugged by the screw bolt 34 for permitting access to the screw 32 for focusing said lamp.

-For actuating said reflector there is a U-shaped member 35 fixedly secured at each 'end to the lower edge of the reflector, as shown in Fig. 4.. v The rear portion of said member is bent inwardly to provide a seat for the actuating lever 36 and is yieldingly connected to the rearof the casing by thespiral springs 37 secured at one end to said member and at the other end to the hook 38 riveted to said casing. This arrangement causes the reflector normally to be drawn back, as shown in Fig. 1, for directing the rays of light downwardly. The actuating lever 36 extends through a suitable slot in the lower portion-of the casing and is fulcrumed to a downwardly extending car 36 thereon at the point 39. It is provided with a recess or any suitable means for engaging the member 35 at its upper end and. is pivotally secured to a cable or" rod 40 at its lower end. On each side of said lever there are downwardly projecting cars 41 and 42 mounted on the lower side of the casing arranged to limit the pivotal movement of said lever and permit the adjustment of said movement b means of thestop screws 43 and 44 exten ing therethrough in position to be engaged by said lever and limiting the movement thereof. For preventing dust from entering through the opening in the lower portion of said casing there is rovided a flexible dust guard 45, suchas c oth, which may be. ce-' mented to the inner surface-and surround the lever 36'. 'Upon pulling back on the cableor rod 40 the lever will force the reflector forwardly into position to direct the rays substantially; parallel with the rod,

and upon releasing the rod 40 the springs 37 will return the reflector to-the normal position shown in Fig. 1. The cable 40 may extend rearwardly through the support 46 from each lamp, as shown in Fig. 5, and pass to suitable pulleys 47 mounted near the dash 48 of the vehicle, thence around the ulleys 49 and up to a pulley 50 having its hub extending through the dash and mounted on a lever 51. The lever 51 is pivoted at 52 on the dash and is provided with a handle 53, whereby upon moving the handle down the'pulley 50 will be raised so as-to draw the cable rearwardly and force the reflector to vertical position. For retaining the reflector iii-vertical position, any suitable arrangement may be used for securing the lever 51 in that position such as friction or pin locking means engaging suitable holes in the dash board. By means of this or a similar arrangement of the cable, the reflectors will be operated by an equal force,

the pulley .50 equalizing the cables through v the springs 54.

The reflector may be readily installed in the casing by hooking the spring 37 on the hook 38, seating the member 35 in position with respect to the lever 38 and then using'a tool to depress thehinge spring 20 to permit the upper portion of the reflector to be hooked over the end thereof.
